It's raining. I could see from the kitchen window that a flower of 'Duchesse de Brabant' was partly open, so I went out and picked it. I couldn't find floral preservative, so I might put a little bleach and a little sugar into the vase. 'Duchesse de Brabant' has a good tea rose fragrance, and it's a delicate shade of pink.
Slightly later: I put in the homemade version of floral preservative. I'll see what happens with that.
